Spring / Spring gRPC Interview Questions

What connection or channel pooling considerations apply when calling gRPC services from Spring?

Because setting up a ManagedChannel involves real connection-establishment cost (DNS resolution, TCP/TLS handshake), the general rule is to create one long-lived channel per target service and reuse it for many calls, rather than building a fresh channel per request - a single HTTP/2 connection can already multiplex many concurrent calls, so there's rarely a need for a traditional connection 'pool' in the way JDBC connections need one.

In Spring, this is handled for you: both the community starter's @GrpcClient-managed stubs and the official Spring gRPC starter keep channels as long-lived, Spring-managed resources tied to bean lifecycle, so application code doesn't need to manage channel creation or teardown manually.

Why don't gRPC channels typically need a traditional connection pool the way JDBC connections do?
How does Spring typically manage gRPC channel lifecycle for injected clients?
